No way to disable without a system property? And it uses STDOUT instead of STDERR?

Edit: For those just wishing to disable it, one good way to set the property is to include a resource file:

src/main/resources/psw4j.properties

global.banner=false

(Removes stdout messages from Password4J)

STDERR is for errors.
The property is documented in the wiki.
